The KBH Vehicle Weight Efficiency Formula

The KBH Vehicle Weight Efficiency Formula multiplies a vehicle's average track-width times its wheelbase-length to arrive at vehicle- platform-square-units. Then the formula divides the vehicle-weight by the vehicle-platform-square-units to arrive at a weight-per-square- unit index value. Finally, the formula uses the vehicle engine-power- per-vehicle-weight as a percentage and reduces the index value by the percentage to arrive at a final index value. The lower the final index value the greater the weight efficiency of the vehicle. Additionally, the final index value could be scaled to convenient output.

Ok, the next logical step is to calculate weight per drag adjusted cubic-unit

gotta use those drag coefficients somewhere. Could be in this formula just as well.

Well, a drag coefficient is an aerodynamic efficiency. In other words the vehicle does define its own purpose and then the aerodynamic efficiency is considered within the scope of the vehicle purpose (with the purpose as a required vehicle frontal size).

And then the KBH Vehicle Weight Efficiency Formula is a weight efficiency. The vehicle does define its own purpose and then the weight efficiency is considerd within the scope of the vehicle purpose (with the purpose as a required vehicle platform size but also considering indicators of frame strength).
